Keynesian model is able to show how leakages and injections can influence the economy. AD-AS model is able to show changes in prices (inflation).
The four sectors in Keynesian macroeconomic model are business, household, foreign sector and government. The Keynesian macroeconomics focuses on a broad scale where the above mentioned sectors play an important role.
The major difference between the classical model and the Keynesian model is their approach to government intervention in the economy. The classical model believes in a hands-off approach, where the economy will naturally correct itself, while the Keynesian model advocates for government intervention to stimulate economic growth and stabilize fluctuations.

In a Keynesian economic model, the multiplier (denoted by γ) is equal to 1/(1 - marginal propensity to consume) or 1/(1 - α), where α is the marginal propensity to consume. When α=0.67 in the consumption function (C = 1/(1 - α)), the multiplier would be 3 (1/(1-0.67) = 3).

The Maxwell model derivation is performed by combining the spring and dashpot elements in series to represent the viscoelastic behavior of a material. The model is derived by analyzing the stress and strain relationships in the system and applying the principles of linear viscoelasticity.

Yes, as no singularity can be observed, mathematical formulation is the only way to model it.
To determine the expenditure multiplier in an economic model, you can use the formula: Expenditure Multiplier 1 / (1 - Marginal Propensity to Consume). The Marginal Propensity to Consume is the proportion of additional income that a person or household spends rather than saves. By calculating this ratio, you can understand how changes in spending affect overall economic activity.
To determine the spending multiplier in an economic model, you can use the formula: Spending Multiplier 1 / (1 - Marginal Propensity to Consume). The Marginal Propensity to Consume is the proportion of additional income that a person or household spends rather than saves. By calculating this value, you can find out how changes in spending will impact the overall economy.
